I was recently experimenting with making PS4 packages of our UE4 game. When running the built package on the PS4 I noticed I couldn’t get our FMOD effects to play. While looking through the logs I noticed this error:

Can you confirm you have this latest version already and that it wasn’t working for you?

I did test the above path string and it worked as far as I could tell, but there are various configurations so I might have missed something. Are you running a code project from within Visual Studio using on-demand cooking, via the editor with “Launch Game”, or are you testing a packaged build?

I was running against FMOD 1.08.01. I just noticed that 1.08.02 was released and it fixes that prx loading line. This appears to fix the issue for me. I’m testing against a packaged build BTW not using the on-demand cooking.
